I have a "tapestry" application which includes a javascript created datepicker which pops up as a javascript created div with an absolute position and a zindex of 400

{Part of code doing this

	// Create the top-level div element
	this._calDiv = document.createElement("div");
	this._calDiv.className = "calendar";
	this._calDiv.style.position = "absolute";
	this._calDiv.style.display = "none";
	this._calDiv.style.border = "1px solid WindowText";
	this._calDiv.style.textAlign = "center";
	this._calDiv.style.background = "Window";
	this._calDiv.style.zIndex = "400";
...
	// Calendar body
	div = document.createElement("div");
	div.className = "calendarBody";
	this._calDiv.appendChild(div);
	this._table = div;
	
...
	this._table.onclick = function (e) {
		// find event
		if (e == null) e = document.parentWindow.event;

...}

A small part of the popped up calender overlays the edge of a large textarea field (with no specified zindex).  In this area of the popped up calender the mouse input does not work, so it is impossible to get at some dates.

As a final check - Mozilla Firefox works correctly where this overlap occurs.

The actual application is security controlled (its the edit function to my personal blog at http://www.chandlerfamily.org.uk), but if someone needs me to set up a demo page temporarily I can do so.
